Answer is:

CH₃-CH₂-CH₂-NH₂ + H₂O(l) ⇄ CH₃-CH₂-CH₂-NH₃⁺(aq) + OH⁻(aq).

Amine group (-NH₂) has neutral charge, bet when accepts one proton (H⁺) has positive charge.
Amines are compounds that contain a basic nitrogen atom with a lone pair of electrons. Amines are derivatives of ammonia, where is one or more hydrogen atoms replaced by a substituent such as an alkyl or aryl group (in this compound propyl group).

Propylamine accepts a proton from water according to the reaction equation; C3H7NH2(aq) + H2O(l) ------> C3H7NH3^+(aq) + OH^-

Propylamine is a base because it accepts a proton. Recall that according to Brownstead - Lowry, a base is any substance that accepts a proton while an acid is any substance that donates a proton. Propylamine accepts a proton because of the lone pair on nitrogen atom.

The reaction of propylamine with water is an acid base reaction because propylamine accepts a proton from water as follows;

C3H7NH2(aq) + H2O(l) ------> C3H7NH3^+(aq) + OH^-
